because of this!
lets start with the only kinda related stuff i have pictures of.
we started working with CF in class this week (actually Friday but whose counting?) we started by cutting a stack of CF squares
then we all took one of the small ones and one of the big ones and then cut circles out of some foam with a 30* incline all the way around
its really cool how easy real CF is to work with. normally when you lay fabric over something round you get wrinkles and stuff but CF is awesome enough that you can actually get stuff like this with just your hands. no special tools or any thing.
then we needed to make a "plug patch" to show how to fix impact or hole damage but to use as an example i used regular Fiber Glass on my patch (my instructor told me too) this was the result after cutting the excess off and making the plug.
now with that out of the way lets move onto the good stuff!
i grabbed a bunch of the scrap CF from my class mates and out of the scrap bin and started laying up rectangular pieces for the faceplate for the motherboard display.
(this one actually got cut in half but i wasn't thinking when i started with the resin)
here is with a couple of layers all laid up and the bubbles pushed out.
then a couple more and the blank i made for size comparison
i eventually had the CF laid 6 layers thick with no bubbles and stuff. but i couldn't get the resin to look like it does on all the car parts and stuff. so i asked my instructor how they do it. he told me they usually "Vacuum form" the parts with one of 4 or 5 processes to make sure every thing is smooth and even. i asked if i could use the schools vacuum system for this but he said no as it would make the jerk that runs the hanger ask questions. but he did give me a suggestion i decided to try.
i took some of the bleeder material that is used between the resin impregnated fabric and the absorbing material when vacuum bagging parts and laid it over top of my rectangles and then took my scraper and pushed out as much of the excess resin as i could with out taking too much and drying the CF out.
this was right after i placed the bleeder ply over the CF. you can already see resin bleeding through the pores
with a little spreading
and this is the final.
i think it should come out quite well. but ill know tomorrow morning when i peal the bleeder off the set CF. but that photo is through the bleeder where i dabbed up as much of the excess resin i could (it was already setting up a little bit.
ill post a picture of the set up CF tomorrow afternoon when i get home from school.
then ill start working on cutting it for the mobo control thing.
i hope it was worth the wait. and because im feeling generous. here is a shot from at the end of the runway this morning on my way to school this morning. it was a bit too clear and i didnt really have time to play though so sorry for the overexposed crap picture
